+  iptables-persistent.service, ip6tables-persistent.service and
+  ipset-persistent.service are now aliases instead of alternatives, using
+  native functionality to provide alternative names. Users wishing to use such
+  names can use 'systemctl enable netfilter-persistent.service' to enable them,
+  and can override them using the standard systemd configuration mechanisms.
+  Other packages wishing to provide the same service names simply have to
+  declare the same aliases in their units, and users can enable the one they
+  prefer.

+netfilter-persistent and its plugins
+------------------------------------
+
+netfilter-persistent does no work on its own. You need the accompanying
+plugins (for example, iptables-persistent) to load and save filter rules.
+
+However, commands are run from netfilter-persistent. For example, to save
+all filter rules:
+
+   netfilter-persistent save
+
+or to load them:
+
+   netfilter-persistent start
+
+For more details, see `man netfilter-persistent`.
+
+The system service will try to load rules at startup if enabled, but by
+default it will not flush rules at shutdown. This behaviour can be changed
+by editing /etc/default/netfilter-persistent.

+  iptables-persistent has become a native package (meaning there is no
+  upstream tarball). In its present form, iptables-persistent is unlikely
+  to be useful outside Debian or Debian-derivatives, and I do not plan to
+  include any support for other distributions, so a native package makes the
+  maintenance overhead considerably smaller.
